Cable Fault Tester

Cable Fault Tester

The MOEORW-WLG02 cable fault tester is a professional testing device with high anti-interference capabilities. It can accurately locate various faults in high and low voltage buried cables and can also detect cable paths and depths.

With its three-channel design, it boasts strong anti-interference capabilities, convenient operation, and suitability for troubleshooting underground cables in various scenarios such as municipal, property, factory, mining, and agricultural settings.

The MOEORW-WLG02 cable fault tester uses electromagnetic induction and step voltage principles to locate open circuits, short circuits, and ground leakage faults (ground insulation resistance within 0.5 megohms) in high and low voltage buried power cables, as well as to detect the depth and path of buried cables.

This system is suitable for various industries including street light cable maintenance, agricultural irrigation cable fault diagnosis and repair, underground armored steel sheet power cables in residential properties and landscaping, outdoor power cables, highways, factories and mines, and direct-buried power supply cables for communication tower base stations . It features a three-channel design: 1. Length Testing: Directly tests the distance of cable breaks and short circuits in the power-off state . 2. Anti-interference Channel: Employs a high-performance filtering circuit to resist power frequency interference. In the power-off state , it works with a signal generator to locate the location of ground leakage in direct-buried cables and measure the cable path and depth. 3. Full-band Channel: In the power-on state, uses a probe to test the location of minor ground leakage faults in direct-buried low-voltage cables. The anti-interference channel adopts a high anti-interference design, ensuring signal reception is not interfered with under high-voltage lines or in cable trench environments.
